一下是利用CSS滤镜效果实现渐变翻转的代码，有需要的朋友可以参考下。
代码如下:
<span style="font-size:14px;"><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css" media="screen">
.ddf{
margin: 0 auto;
width:150px;
height:125px;
background:#92B901;
color:#ffffff;
font-weight:bold;
font:12px '微软雅黑', Verdana, Arial, Helvetica, sans-serif;
padding:20px 10px 0px 10px;
-moz-transition-property:width,height,-o-transform,background,font-size,opacity;
-moz-transition-duration:1s,1s,1s,1s,1s,1s;
<span style="color:#FF0000;">transition-property:width,height,transform,background,font-size,opacity;</span>
<span style="color:#FF0000;">transition-duration:1s,1s,1s,1s,1s,1s</span>;
border-radius:5px;
opacity:0.4;
}
.ddf:hover{
-moz-transform: rotate(360deg);
transform: rotate(360deg);
opacity:1;
background:#1ec7e6;
width:90px;
height:60px;
font-size:16px;
}
</style>
</head>
<body>
<div class="ddf">转着好玩</div>
</body>
</html>
CSS中transform: rotate(<span style="color:#FF0000;">360deg</span>);旋转，默认顺时针旋转参数为度数例如：360deg
</span><pre name="code" class="html"><span style="font-size:14px;">transition-property:过滤，后面接需要过滤的属性例如：</span><span style="font-size:14px;">width,height,transform,background,font-size,</span><span style="font-size:14px;"></span>
<span style="font-size:14px;">transition-duration:后面接相应过滤属性的执行时间。</span><span style="font-size:14px;"></span><pre name="code" class="html"><span style="font-size:14px;"></span><pre name="code" class="html"><span style="font-size:14px;"></span><pre name="code" class="html"><span style="font-size:14px;"></span><pre name="code" class="html"><span style="font-size:14px;"></span><pre name="code" class="html"><span style="font-size:14px;">opacity：</span>规定不透明度。从 0.0 （完全透明）到 1.0（完全不透明）。
